CLEARING-WING FOR DITCHING-MACHINES.

Specification of Letters Patent.

Patented. Oct. 22, 1907.

Application filed January 26, 1907. Serial No. 354: 196.

To all whom it may concern:

Be it known that I, WALTER UMSTEAD, a citizen of the United States, anda resident of Jerseytown, in the county of Columbia and State ofPennsylvania, have invented a new and useful Improvement in Clearing-Wings for Ditching-Machines, of which the following is a full, clear,and exact description.

The purpose of the invention is to provide a clearing wing particularlyadapted for the ditching machine for which an application for patent wasfiled by me February 21, 1905, Serial No. 302,305, and which was allowedNovember 5, 1906. The object being to provide a wing of simple, durableand economic construction capable of attachment to most every type ofditcher, and by reason of its shape and peculiar construction will moveunder the loose earth, being held down to its work by the weight of thegathered earth, and which will not dig into or otherwise destroy thebank. And furthermore, to provide a simple guide for the wing and meanswhereby it will automatically accommodate itself to the surface of theground at the bank no matter what the depth of the ditch may be, andalso accommodate itself to any pitch of the plow.

The invention consists in the novel construction and combination of theseveral parts as will be hereinafter fully set forth and pointed out inthe claims. Reference is to be had to the accompanying drawings forminga part of this specification, in which similar characters of referenceindicate corresponding parts in all the figures.

Figure 1 is a rear elevation of a portion of a ditching machine, and aperspective view of the improved wing applied; Fig. 2 is a horizontalsection through the wing and parts of the machine connected therewithand adjacent thereto; and Fig. 3 isa perspective of the improved wingviewed from the rear.

A represents an arched axle of a ditching machine provided with thecustomary spindles a, upon which the supporting wheels 10 of the machineare mounted to turn. A hanger 11 is shown extending down from the archedaxle A at a point to one side of its center, being pivotally attached tothe said axle, and this hanger is shown terminating in an arm 12 havinga downward extension 13 that engages with one side of the ditch as theditch is made by the plow B. This downward extension or arm 13 isattached to a standard 14, in fact the downward extension 13 may betermed a support for said standard. This standard is provided at itsupper end with horizontal bearings 15 and a second standard 16 isattached to the first-named standard 14 at its upper portion, andextends therefrom downward and outward, and it is parallel with thelowerportion of the standard 14, and the said standard 16 at its lowerportion engages with the opposite side of the ditch, as is shown in Fig.1.

decided concavity 19 in its upward face.

end of the said wing and that point at or about the center, v

An angular bracket 1'7 is attached to the inner face of the lowerportion of the standard 16,'as is also shown in Fig. 1, and a rod 18 issecured at its upper end to the ear 15 of the standard 14:, and at itslower end is secured to the said angular bracket 17, as is also shown inFig. 1. This rod 18 is adapted as the prime guide for the wing O. Thiswing is provided at its outer end with a The inner is also provided witha concavity 20, but much less in depth than the concavity 19, in factthe concave forward face of the said wing C may be made to graduallydiminish from the point near its center to its inner end. A lip 21 isformed at the lower edge of the decidedly outer concavity portion 19,and the said lip is inclined or is beveled off at its inner end where itconnects with the lesser inclined face 20 of the said wing, as isparticularly shown in Fig. 2, and by reference to Fig. 3, it will beobserved that the rear face 22 of the said wing at its outer end is asdecidedly convexed as is its correspondingly inner face 19 concaved.

A bracket 23 is used in connection with the wing G, and the inner end ofthe wing O is pivoted to the lower body portion of the bracket 23, as isbest shown at 23"" in Fig. 1. This bracket 23 is provided with an upperear 24 and a corresponding lower ear 25, and both of these ears areprovided with corresponding apertures through which the guide rod 18heretofore mentioned, freely passes, so that the wing C is capable ofvertical guided movement to accommodate itself to the bank of a ditchirrespective of its depth, but the wing O is held down to its work atthe brink of the bank by means of a spring 26 which is preferablyattached to the upper ear 24 of the bracket 23, and to the lower portionof the standard 14, as is best shown in Fig. 1. The lip 21 extendingwith its decided forward curve, yet with a smooth and unbroken rearlower edge portion, passes beneath the earth thrown up by the machine,and the weight of the earth thereon keeps it from rising and riding overthe same, thus producing a perfect clearance of the earth in advance ofthe wing.

The wing has a second guide, which is in the nature of a rearwardlyextending arm C that is located diagonally with reference to the rear ofthe wing, and this arm 0 is secured to the bottom horizontal plate 26that moves smoothly over the ground as the wing 0 advances. This guidearm 0 is provided with an up-v ward and rearwardly inclined section 27intermediate of its ends, and a horizontal rear terminal portion 28, inwhich a recess 29 is made adapted to receive the straight portion of thestandard 16, and a downwardly extending lip 30 for guided engagementwith said standard, as is clearly shown in Fig. 1. The support 13, as isshown in Fig. 2, serves to hold the plow point B in proper position forwork, and its accompanying mold board B, the plow point being locatedbetween the lower end portions of the standards 16 and 26, as is clearlyshown in Fig. 1.

It is evident that a wing of the character described is readilyapplicable to almost every type of a ditching machine. It is very simpleand is economic in its con struction as has been stated, and isautomatic in its action.

Having thus described my invention, I claim as new and desire to secureby Letters Patent,- V

1. A clearing wing for ditching machines, having a dccided concavity atits outer end and a lesser concavity at its central and inner endportion, a standard to which the wing is pivoted, and a guide armextending from the rear of the wing,

12. A clearing wing for ditching machines, having its outer frontsurface decidedly concaved, the remaining portion of its forward surfacehaving a lesser concavity, and a lip at the lower edge of the forwardportion of the said wing constituting a continuation of the concavedsurface at such point.

3. A clearing wing for ditching machines, having its outer front surfacedecidedly concaved, the remaining portion of its forward surface havinga lesser concavity, and a lip at the lower edge of the forward portionof the said wing constituting a continuation of the concaved surface atsuch point, a rearwardly extending flat member at the lower inner edgeportion of the wing, a guide member secured to said flat portion, and aslidable bracket to which the inner lower end portion of the wing ispivoted.

4. A clearing wing for ditching machines, having its outer front surfacedecidedly concaved, the remaining p0rtion of its forward surface havinga lesser concavity, and a lip at the lower edge of the forward portion01' the said wing constituting a continuation of the concaved surface atsuch point, a rearwardly extending fiat member at the lower inner edgeportion of the wing, a guide member se cured to said flat portion, aslid-able bracket to which the inner lower end portion of the wing ispivoted, a support upon which the said bracket has sliding movement, astandard with which the rear guide arm engages, and means fortensionally holding the wing to its work.

A clearing wing for ditching machines, having a concaved forward face,the concavity diminishing in pronouncedness from its outer end indirection of its inner end, being least pronounced at the latter point.

(5. A clearing wing for ditching machines, having a concaved forwardface, the concavity diminishing in pronouncedness from its outer end indirecting of its inner end, being least pronounced at the latter point,and guide devices connected with the rear of the wing.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
